Figure Legend Snippet: a . Boxplots showing statistically significant (*p<0.05, ANOVA with Fisher’s LSD) elements tested in luciferase assays in iCell GlutaNeurons. b. Boxplots showing statistically significant (*p<0.05, ANOVA with Fisher’s LSD) elements tested in luciferase assays in KOLF2.1J-hNGN2 neurons. c. RT-qPCR of MAPT expression. Barplots show statistically significant regions tested in Day 14 BrainPhys differentiated neurons by CRISPRi experiments. Red asterisk indicates regions significant by 3’ mRNA-seq and RT-qPCR. Gray asterisk indicates regions significant in either RT-qPCR or 3’ mRNA-seq. (*p<0.05, ANOVA with Fisher’s LSD). d. Heatmap showing differential expression of MAPT and all genes expressed (cpm > 30) within 1 Mb of MAPT TSS. Left y-axis indicates the distance of the midpoint of the target region tested in CRISPRi experiments from the MAPT promoter (chr17:45894000). e. Browser view of significant nominated regions. Green: iCell GlutaNeuron luciferase assay. Blue: KOLF2.1J-hNGN2 neuron luciferase assay. Teal: CRISPRi. Red: significant in luciferase and CRISPRi. f. – i. Key CREs regulating MAPT expression. Zoom in on regions validated by qPCR and CRISPRi ( f. −652,338, g. −464,677 & −461,949, h. −44,905, i. 48,416). Top panel: Normalized Accessibility from KOLF2.1J-hNGN2 differentiated Neurons. Bottom panel: Tracks of design region, luciferase region (Green: tested in iCell Gluta Neurons; Blue: tested in KOLF2.1J-hNGN2 neurons; *p<0.05, ANOVA with Fisher’s LSD), gRNA position, and nominated regions (DLPFC Links: Blue: control-specific link; gray: common link; Red: AD-specific link).
